Where do Halion sampler .vstpresets live?

I have several sample sets of ethnic percussion hits and loops, recorded at a very high quality and I would like to share them for free.
However I need to also be able to pass on the saved keymaps saved as .vstpreset.
So I need to find what directory /folder /path where they live, both on mac osx and windows.
I am using a mac running osx 10.9.5 and I have searched in all the obvious directories like library/audio/steinberg media technologies etc.
I have also tried using the find/search option, but I just can’t find them anywhere.
Any help would be appreciated.
